To all whom, 'z't may concern.'

Be it known that l, THOMAS R. JENKINS, Jr., a citizen of the United States, residing at Baltimore, in the State ofMaryla-nd, have invented certain new and useful Improve ments in TruclcReels for Conductor-Ylfi'es, of which the :following is a specification.

This invention relates to a reel for winding,l the electric conducting wires communi# eating 'between a` source of current and a inotorwboth said reel and motor being supported on 'a frame mounted upon rollers which carry also any desired apparat-us `to be drivenby 'the meten-such as a rot-ary scrubbing machine, a vacuum sweeper or other machine.

The object of this invent-ion is to provide an improved construction of gearing and revoluble reel on which the conducting wires will be automatically wound and unwound the apparatus moves forward or hackivard andto combine the saine with such apparatiis7 so as to avoid .dragging the wires of lthe reel.

a simil Y along the floor.

The invention is illustrated in the accompanying drawing, in which, parts of a supporting, frame mounted on rollers, a motor, f zonductin'gwires, and one side of the reel. Fig. 2 is);Y top view, on a larger scale, Fin/j. 3 shows ythe contact side of the reel-which side 'is opposite that. seen in Fig. 1. Fig. 4' is a detail view of the Wire holder device that makes Contact withathe The horizontal .line 1, indicates a floor; the circular line, 2, one of the rollers that support the apparatus and which `is to move forward and backward on the floor. The i'iranie sho wn in Fig. 1, illustra-tes those parts ot' 'the `frame that are seen at one side only.

rif'he numeral, 3, designates one .of the :base bars `which has head, 1 provided with a hole, 5, that indicates a bearing to take the aided-od on which latter the 4rollers maj,7 turn. The vertical bar, 6, has itslower end attached to -the base bar, 3, and at its Atop i at 7, and extends horizontally across opposite 'side of the apparatus, where ar vertical bar (not seen) is attached in like manner to the base bar at that side. ,it cach side oi the it'raine is an upwardlyinclincd pushfba r, 8, which has-its lower end bolted to the usehar, 3; atthe Vtop end or" passes the cable,

'center of the horizontal 'oar that extends -from 'the curve, 7,

across to the opposite side; at its top end this sta-ii has a h'ook, 11,

tosustain a pulley block, '12, over which n 13, inclosing; the two conducting wires. A brace rod, 14, has its lower end secured to one of the inclined push bars, 8,v and itsy -upper end is secured to the, steli", 10, nea-r its top. In practice two such brace rods Iare or may be used;

A horizontal bar, 15, has one end Secured to the'vertical bar, (3, and the other end secured to the inclined push bar, 8, and a standard, 16, has an end attached to the baseebar, 3, and therefrom extends upward and is attached by a bolt, 17, lto the'inclined push bar, and its upper end is secured to the said. horizontal bar, 15. I

The revoluble reel, (d, is supported .and turns on a horizontal rod, 18, which latter rest-s in bez'iring's, 19,.one end of said rod being in such a bearin'T that seats on each of two horizontal bars, 15. i

It will be seen this construction of frame mounted on rollers constitutes ,ai truck and' provides for supporting the reel, C; for sus: tain-ing at an elevated position the pulleyblock, 12, that holds up the cable and also provides for bracing the structure parts.

A motor, 20, is supported on a bracket, 2l; this motor vis to' drive the mechanism (not shown) whatever it maybe; in the present instance the mechanism referred' 'to is intended for scrubbing the floor by the action of rotary brushes, which, however, is no part of the presentinvcntion. u

The horizonte-.l rod, 18, already eX- plainedlias its ends sustained in the/two bearings, 19, 4which latter are seated on thei two horizontal bars, 15, and said rod, 18, is rigidlyfne'ld in the bearings -by'ni'eans o15 set bolts, Thus' it will beiinderstood t disks, 23, and, 24, iespectivclyrfhicli held in the spaced-apart condition by Tha G a c Ud Hg y h l makes n.

ma end 'ters Patent is zthe reel will unwind the Conductor but at the same time will Wind the spring, 42,-- tlie gearing being such that no appreciable diierence is noticedby the operator as the spring Winds. By this means the cable is kept sufiioiently taut to keep it off the floor or surface about the machine so it Will not interfere with the manipulation of the chine.

Having thus described' my invention what claim and desire to secure by Let- A truck-ree1 for Winding the conducting Wires oa rotary floor-scrubbing maclilne having 1n combination, a fixed horizontal rodg-a reel on which the conducting Wires may be Wound-said reel having twodisks rotatably mounted on the said rod one of the disks being provided with a sleeve 28 loose around the rod; a stationary vertical H plate rigidly supported on said rod between the two disks; a second sleeve loose on the rod; a bracket arm rigidly secured to the said rod intermediate of said two sleeves and said arm projecting andhaving a shaftbearing, 33; a spring coiled around the rod
